Dan Gohman bf8e5204d1 Update these argument lists for the isNormalMemory
argument. This doesn't affect current functionality.

Dan Gohman 79c3516912 Use a latency value of 0 for the artificial edges inserted by
AddPseudoTwoAddrDeps. This lets the scheduling infrastructure
avoid recalculating node heights. In very large testcases this
was a major bottleneck. Thanks to Roman Levenstein for finding
this!

As a side effect, fold-pcmpeqd-0.ll is now scheduled better
and it no longer requires spilling on x86-32.

Chris Lattner 2fdcc59bb6 Change m_ConstantInt and m_SelectCst to take their constant integers
as template arguments instead of as instance variables, exposing more
optimization opportunities to the compiler earlier.

This fixes an instcombine crash on PR3235.

Sebastian Redl baad4e765f PODness and Type Traits
Make C++ classes track the POD property (C++ [class]p4)
Track the existence of a copy assignment operator.
Implicitly declare the copy assignment operator if none is provided.
Implement most of the parsing job for the G++ type traits extension.
Fully implement the low-hanging fruit of the type traits:
__is_pod: Whether a type is a POD.
__is_class: Whether a type is a (non-union) class.
__is_union: Whether a type is a union.
__is_enum: Whether a type is an enum.
__is_polymorphic: Whether a type is polymorphic (C++ [class.virtual]p1).

In fact this also deletes those with linkonce linkage,
however this is currently dead because for the moment
aliases aren't allowed to have this linkage type.

Daniel Dunbar 6e01600398 Add prototype ccc rewrite.
- Entry point is tools/ccc/xcc until we are a functional replacement
   for ccc.

This is highly experimental (FIXME/LOC ratio of 3.4%), quite crufty,
and barely usable (and then only on my specific Darwin). However, many
of the right ideas are present, and it already fixes a number of
things gcc gets wrong.

The major missing component is argument translation for tools
(translating driver arguments into cc1/ld/as/etc. arguments). This is
a large part of the driver functionality and will probably double the
LOC, but my hope is that the current architecture is relatively
stable.

Documentation & motivation to follow soon...

Douglas Gregor 07665a69e8 Introduce support for "transparent" DeclContexts, which are
DeclContexts whose members are visible from enclosing DeclContexts up
to (and including) the innermost enclosing non-transparent
DeclContexts. Transparent DeclContexts unify the mechanism to be used
for various language features, including C enumerations, anonymous
unions, C++0x inline namespaces, and C++ linkage
specifications. Please refer to the documentation in the Clang
internals manual for more information.

Only enumerations and linkage specifications currently use transparent
DeclContexts.

Still to do: use transparent DeclContexts to implement anonymous
unions and GCC's anonymous structs extension, and, later, the C++0x
features. We also need to tighten up the DeclContext/ScopedDecl link
to ensure that every ScopedDecl is in a single DeclContext, which
will ensure that we can then enforce ownership and reduce the memory
footprint of DeclContext.
